AUTOMOBILE JACK.

Application 11ed'March` 11, 1926, ,Serial No. 93,962.y

This invention relates to automobile ,jacks and more .particularly to a jack for l,use in unloading automobiles from the carin which they Vare shipped.

iin important object of the invention is to providea Adevice of this character which may be employed to support'the car lwhile the usual .ii-frames by means of which the forward ends of the cars are usually supported may be removed and which may subsequently be employed to lower the car to a horizontal position.

A further object of the invention is to produce a device of this character which is additionally usable in worl` in and about the garage wherever one end of the car is to be elevated for any purpose, such as removal of a wheel or the like.

A still further object is to produce a device of this character which may be relatively cheaply constructed, which will be durable and eiiicient in service and a. general improvement in the art.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of mv invention and wherein 'Figure 1 is a fragmentary sectional view through a freight car showing' a jack constructed in accordance with my invent-ion in use to support the forward end of an automobile preparatory to removing the auto mobile from a car; v

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a section Figure 1;

Figure view taken through nism of the jack;

Figure 5 is a section on Figure 2.

Referring` now more particularly to the drawings, the numeral indicates a frame which is substantially U-shaped and is preferablv formed from a single length of angle iron having' its horizontally disposed angle 11 inwardly arranged and disposed at the lower side of the frame. This frame is supported at its bight end by casters 12 and at on the line 3 3 of t is anenlarged detail sectional the line 5-5 of its opposite end by supporting wheels 13.

preferably mounted upon an aXle 14 conneet-ing the arms 15 of the U. The arms of the frame are connected by suitable braces 16, one of which is arranged adjacent the the operating mechabight lportion 17 of the. frame and provides a seat for thelower end ofa worm shaft 18. This seat is in the form of asoclret 19 elongated transversely of thefframe and the end of the shaft 18 is flattened 4to lit within the socket sothat the shaft mayrockin a plane longitudinally bisecting theframe but is held against rotation. A supplemental orswinging frame 2O isprovided which is likewise U-shaped and formed of angle iron. In this frame, however, the horizontal angle 21- is arranged uppermost and inwardly directed and the frame is of such size that the vertical angle will ht about the vertical angle of the frame 10 when the frame 20 is in its lowermost position. This frame has the ends of its arm 22 pivotally connected to the ends of the arms 15 of the frame 10 preferably by the axle 1d, hereinbefore mentioned.

Immediately adjacent its bight portion 23, the frame has pivotally connected to its arms 2i., the arms 24 of a U-shaped yole 25 having at the center of its bight an opening 26 for the passage of the worm 18. Immediately beneath the bight of the yolte and engaging thereagainst is a gear nut- 27 for the worm 18 and the arms 24 provide a means for supporting a cranlr yoke 28 in which is longitudinally mounted a cranlr 29, the inner end of which is provided with a gear 30 meshingwith the gear nut 27. At a point spaced a short distance from the bight 23 of the frame 20, the arms 22 thereof are bridged by an inverted U-shaped support 31 formed of channel iron and having the channel thereof outwardly arranged. To the arms at corresponding points further spaced from the bight 23 are secured angle brackets 32.

In the use of the device for unloading shipping cars, the. jack is rolled beneath the automobile, the forward end of which is supported by A-frames 33 and the supplen'iental.

or swinging frame 2O adjusted upwardly until the axle 34C of the automobile is supported from the channel bridge 31 and is engaged within the channel thereof. The A-frames are then removed and the automobile may be shifted within the car either with its forward end elevated and supported in this manner or this forward end may firstbe lowered until the automobile is in substantially horizontal position. It will be noted that the bight portion of the frames is of considerably less width than the normal width of an automobile so that ample clearance is provided to enable application of the front Wheels to the axle While the device is still supported. from the jack. lt will, ot course, be obvious that the jack can be employed for ordinary garage use n the usual manner.

Since the construction hereinbefore set forth is capable of a certain range oi change and modification Without materiall;7 departing' from the spirit of the invention, l do not limit myself to such speciic structure except as hereinafter claimed.

I claim:-

In an automobile jack, a Wheel supported main frame, Said frame being U-shaped, a second U-shaped frame having the arme thereof pivoted to the arms or the first named frame, a connection between the adjacent to but spaced from the 'bridge member.

In testimony whereof l signature.
